Orient Display LCD displays are the general category that includes LCD display glass panels, character LCD modules, graphic lcd modules, Arduino LCD displays, and our featured JAZZ series graphic LCD displays.

Graphic LCD Displays: Our standard LCD Graphic display products range from 122 x 32 pixels to 320 x 240-pixel resolution. These displays are available in positive or negative STN, blue STN, FSTN, or FFSTN with multiple backlight color options. They can be either traditional Chip-On-Board (COB) LCDs or Chip-On-Glass (COG) LCDs for displays with a smaller footprint and lower power consumption. COGs come in the same display types and colors as our other LCD modules but are designed without a PCB to allow for a slimmer profile.

JAZZ Graphic LCD Displays: The series are exclusive for Orient Display 128 x 64 pixels with the selection of yellow green STN, blue STN, positive or negative FSTN display, with the options of yellow green, green amber, blue, red or RGB tricolor backlights, with or without resistive touch panels. JAZZ series have two sizes: 1.0” and 2.7”.

VTN Character LCD Displays: Orient Display VTN is vertical alignment LCDs which provide superior black background and then great contrast with the options of yellow green, green amber, blue, red or RGB tricolor backlights.

LCD Glass Screens (Panels): Orient Display LCD display panels include different options of polarizer in reflective (saving power), transmissive (better contrast) or transflective (sunlight readable and battery powered) types. Orient LCD glass panels include 1; 2; 2.1/2; 3; 3.1/2; 3.3/4; 4; 4.1/2; 5; 6; 8; and 24 digits. Orient LCD glass panels also include 7 , 14 or 16 segments to display digits and alphanumeric letters. The temperature ranges are from room temperature to wide temperature applications. Orient LCD glass panels can have metal pin or zebra connections.

ARDUINO LCD Displays: Orient Display creates special character LCD displays with SPI interface which is easily hooked up with Arduino, which has been widely acceptable in the electronic design. The series includes 8 x 2 characters, 16 x 2 characters, 20 x 2 characters and 20 x 4 characters with either yellow green STN with yellow green LED backlight or blue STN with white LED backlight.

Although Orient Display provides many standard small size OLED, TN or IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

If you have any questions about Orient Display TFT LCD displays or if you can’t find a suitable product on our website. Please feel free to contact our engineers for details.

LCD (Liquid Crystal Displays) have two options or display modes.Positive mode (dark characters on a light colored background) and negative mode (lighter colored characters on a darker background).

Please see Fig.1: Yellow green STN (Super Twisted Nematic) display, the background of yellow green is lighter than dark blue characters. It is a positive mode. Fig. 2 is a blue STN display, its background of blue is darker than the white characters.It is negative mode.

But under bright ambient light or even under direct sunlight, the displays will be easily washed out. In order to be seen under the bright surrounding light, the backlight brightness has to be increased to over 800 nits. The sunlight readable displays consume much power.

Of course, we can always use LED backlight in the LCD module with fewer LED chips and turn off LED backlight when not use to save power. When can also add transflective polarizer to some negative LCDs to make it sunlight readable, but the contrast will be compromised.

Positive and negative mode concept is not only limited to monochrome LCD displays (LCD panels, character LCDs, graphic LCDs etc.), it also uses for color displays, or even other display technologies.  We will categorize the displays as below,

Character LCD modules (Alphanumeric LCD display modules) with character sets: 8×1 LCD display, 8×2 LCD display, 16×1 LCD display, 16×2 LCD display, 16×4 LCD display, 20×2 LCD display, 20×4 LCD display, 24×2 LCD display, 40×2 LCD display, 40×4 LCD display.
